Introduction

When it comes to the Revolutionary War, one of the only generals that most Americans can name today is George Washington, who went on to become our nation's first president. Washington commanded the Continental Army for the entire war and led that army and the nation to victory. However, that victory would not have been possible if not for contributing efforts from other generals. Of those contributing generals, few, if any, were more important than Henry Knox.

Knox was a man who played a pivotal role in the American Revolution. A Massachusetts native, Knox was born in 1750, not long before the American Revolution began. He attended a few years of formal schooling and worked in a Boston store during his early years. At the age of 18, Knox joined a Boston-area artillery company, serving as a militia unit at that time. He soon put his experience as a clerk in a bookstore to good use when he opened his own bookstore in 1771. Having an interest in the military, Knox sold many books on military history and military tactics.

During the early 1770s, Knox was a strong supporter of the growing patriot movement. He witnessed the Boston Massacre in 1770 and supported the Sons of Liberty patriot group in Boston. He married Lucy Flucker in 1774, and despite her loyalist parents, Knox continued his support of patriot groups and his resistance to British colonial policy.

Revolution

In 1775, when bloodshed began between the British and colonial forces and the former laid siege to Boston, Knox and his wife fled the city and Knox joined the colonial forces. He played a key role in establishing artillery positions around Boston, using engineering and military skills which he had learned through his book trade to assist colonial forces.

In the summer of 1775, George Washington took notice of young Knox, then only 25 years old, and a strong friendship began. Knox was commissioned as a colonel in an artillery regiment. He led an important expedition to garner cannons from Fort Ticonderoga in northern New York. Leading a team of men and oxen through the snow in December 1775, Knox got the cannon to Boston by January 1776 in one of the most remarkable accomplishments of the Revolutionary War. The guns were instrumental in the colonial forces breaking the British grip on Boston that spring.

General Knox

Throughout 1776, Knox played an important role as Washington and the Continental Army survived several losing campaigns. In December 1776, Knox participated in Washington's Crossing of the Delaware and subsequent victories at Trenton and Princeton. Following the victory at Trenton, Knox became a Brigadier General. He used his new rank to improve the artillery capabilities of the Continental Army and in 1777 fought with the army in the field.

Throughout the rest of the war, Knox was a vital part of the leadership of the Continental Army. As the army grew and became more experienced, so did Knox, who was in his late 20s at the time. Knox can be credited with the development of the army's artillery during the war, a key contribution to the army's ultimate victory at the Siege of Yorktown in 1781. At Yorktown, the field artillery which Knox placed and supervised was indispensable; it helped to keep the British in their fortifications and eventually forced the British surrender, along with the presence of French artillery and the French navy.

Secretary Knox

In 1782, Knox became a Major General in the army. In 1783, when Washington resigned and returned to private life (for only a short time), Knox was given command of what remained of the standing Continental Army. He organized the Society of the Cincinnati, a group of Revolutionary War officers who banded together after the war as a fraternal organization.

In 1785, Henry Knox became the Secretary at War for the United States. In this post, he oversaw a small peace-time standing army. Knox kept this role when George Washington became the nation's first president. Under Washington, he became a member of the president's cabinet and his role was titled as Secretary of War.
